NAMEprotocols -- protocol name data base
DESCRIPTION
The protocols file contains information regarding the known protocols
used in the DARPA Internet. For each protocol a single line should be
present with the following information:
official protocol name
protocol number
aliases
Items are separated by any number of blanks and/or tab characters. A
hash (``#'') indicates the beginning of a comment; characters up to the
end of the line are not interpreted by routines which search the file.
Protocol names may contain any printable character other than a field
delimiter, newline, or comment character.
FILES
